Thank you John and Paul,
I started having a look into the systemfit.
Basically, my two equations are:
1. Y = IV1 + IV2 x X
2. Y = a + b x X + u
where Y and X are the two endogenous variables, IV1 and IV2 are the
instruments, and u is the error term.

Dear Arne
Generally I would have the following equations X_i = IV3_i + IV4_i * Y_i
applying for every company (i). In a first step, I am interested in
estimating the relationship between X and Y: Y_i = a + b * X_i + u to
ultimatly estimate X_i by substituting the Y_i and solving for X_i to be
The challenge is to firstly calculate the reduced form. As far as I know, the
SEM package does not do this automatically. Am I correct?

Right. If you look at the code in sem:::tsls.default, you'll
